. 15 Claims. It is well known to those skilled inthe art that in paper making machines of the Fourdrinier' typ the woven wire screen or endless apron must frequently be replaced. In present practice, when such repairs are to be made, practically all of the wet end of the machine must be dismantled, requiring the removal'of the endless deckles, supports, rolls, suction boxes, trays,-

apron boards, etc., and the subsequent replacement thereof.

It has been the principal object 'of'my invention to provide means whereby the wire screen or endless apron of a Fourdrinier machine may be easily and quickly removed from the machine without the usual expenditure of time and labor in dismantling parts thereof. v

Another object has been to do away with the customary endless deckle straps and to provide in their places deckleswhich maybe easily and quickly removed when it is necessaryto' change the apron.

A further object is to provide a slice member having an edge which may be adjusted'to a line degree of accuracy.

Moreover, my invention contemplates the use of an outlet box movably connected to the head box of a paper making machine and provided with means whereby it can be quickly moved out of the way without having to be disassembled or re- 30 moved from the machine.

Furthermore, my invention is so designed that the changing of the woven wire screen or endless apron of a Fourdrinier machine may be made with the expenditure of very little time and labor.

Moreover, in my invention, the apron extending to the breast roll'is carried by the outlet box.

The above objects and advantages have been accomplished by the device shown in the accompanying drawings, of which:

Referring to the form of invention shown in Figs. 1 to '7, inclusive, my invention is to be appiied'to the head-box III of the ordinary Fourdrinier machine, and comprises, in general, an 10 outlet box mounted upon a platform l2 and arranged in telescoped relation with the-head box III of the machine. This outlet box carries the slice l3 and the deckles M. For convenience of illustration, I have shown only the breast roll IS, the table or frame ll of a Fourdrinier machine, and a number of" table rolls l6, together with a portion of the wire screen l8.

The outlet box H comprises two side walls and 2| which have their outer faces in engage- 20 ment with the inner faces, respectively, of the side walls 22 and 23 of the head box. The outlet box is also provided with a bottom 24 which is, of course, secured to the side walls 20 and 2| and which is supported on suitable tracks 25 carried 25 by the supporting platform l2. The platform is, of course, arranged immediately in front of the breast roll l5 and the parts are so designed that the bottom 24 extends forwardly to a point near the vertical center line of the breast roll, as shown in Fig. 4, when the outlet box is in its working'position. Extending across therearcdge of the bottom 24 of the outlet box, is an angle iron 26, the vertical leg 21 thereof being preferably flush with the inside edged the bottom. The horizontal-leg 28 is preferably of the same thickness as the tracks", and a packing strip 29 is carried by the platform l2 'and engagesjwith the legs 21 and 28 of the angle iron 26, whereby the bottom of the outlet box is sealed.

A shaft 43 is suitably carried by the walls 22 and 23 of the head box I0 and in such position as to be.located some distance above the walls 4 20 and 2| of the outletbox. This shaft is pro- 1 vided witha hand wheel .44 whereby it may be rotated. Also carried by the shaft 43. are two gear pinions 51 which are arranged over-the walls outlet box is in' its normal position, and thus prevent leakage between such side walls.

As shown in Figs. 3 to 6, inclusive, the forward edge of the bottom of the outlet box is provided with a recess 30 in which is disposed the rear edge of a flexible apron 3|. This-apronextends forwardly to a point substantially over the vertical center lineof the breast roll I. The recess 30 extends clear across the forward edge of the bottom and is of a depth equal to substantially onehalf the thickness of the bottom. Arranged on top of the apron 3| and within the recess is an apron retaining plate 32 which is held in place by a plurality of screws 33 having their heads 34 counter sunk flush with the top of the retaining plate. The retaining plate is of "such thickness that when in place, it is level with the top surface of the bottom 24 of the box. The sidewalls I0 and 2| of the box are so shaped that the lower edge surface 38 of each extends forwardly beyond the forward edge of 'the bottom Ila distance slightly beyond the vertical center line of the breast roll ll. Such surfacedsprefe'rably in the same plane as the top surface of the bottom 24.

The recess 3|! cut in the forward edge of. the bottomextends clear across the bottom and under the side walls 20' and 2|, whereby the flexible apron 3| may be passed under the surfaces 35 of the side walls and up on the outside surfaces thereof, as shown in the drawings and particularly in Fig. '7. The apron is made of such length that its ends 38 can be brought up on the outside ofthe surfaces of the walls a considerable distance. These ends are secured in place preferably by means of a clamp plate 31 carried by each side wall of the outlet box'and retained in place by means of cap screws 33 which pass through the plates andthe ends 3 of the apron and are screwthreaded into the sidewalls. Due to the .fact that the recess 30 is formed underrthe side walls'20 and 2|, the retaining plate 32 also extends under these side walls and on top of the apron.

' is formed in the inner face of each of the side wallsv 20 and 2| and located preferably a short distance behind the surfacejll of the wall for the receptionof the vertical edges of the slice I3. Each of these grooves extends down to .within a short distance-from the surface .35 of the wall, as clearly shown in Fig. 5, whereby ledges 46 are provided which act as stops in the event that the adjusting screws should allow theslice to move downwardly beyond its adjustedposition. Carriedon the inner face of each of the sidewalls is a vertically arranged guide member 41. This guide member is preferably angular in crosssection and one of its legs 48 is secured to the side wall. The other leg of the member extends inwardly toward the center of the outlet box and is so positioned that its face will. be coincident with the fr'ont; face of the groove 45. A groove 50 is formed in'the leg I! of this member, and a ridge ll, formed near the vertical edge at each side of the slice, is designed to engage with and be guided by this groove.

"The overhanging portions of the side walls 20 and 2| are preferably connected together by purpose of stiffening the structure and supporting the slice I3 at one point or a number of points throughout its length. and may carry one or more rings 53 held in place by screws 54 and carrying an adjustable screw or bolt 55, the head of which is brought to-bear against the outer surface'of the slice l3. When the bolt 55 has been adjusted so as to place the proper pressure upon the slice, it is set in such adjusted position by means of a lock nut 55 carried thereon. For clearness of illustration, I have shown but one ring 53 arranged at the center of the slice, but obviously,

any number may be employed, depending upon 'the amount of support required by the slice.

The slice 3 has an angle iron member 60 secured along its upper edge and, carried at each end of this member, is an arm 6| which projects above the member and out beyond the end thereof. Each of these arms carry an adjusting screw 02 having a lock nut 63. Each adjusting screw extends downwardly and engages an angle iron member 64, carried by each 'of the side walls ll and -2| of the outlet box and arranged on the outer surfaces thereof. By means of these screws. the vertical position of the slice l3 may be adjusted.

The slice l3 of my invention does not extend down to, the wire screen l8, but it is provided atits lower end with an adjustable slice member 88. This member is preferably made of some flexible material. such as rubber, and it is disposed on the inside surface of the slice l3-and is held in place by a number of bolts 86.. These bolts pass through slots 61 formed in the lower portion of the slice l3, whereby the member may be vertically adjusted. Each of the bolts extends through the center of the slots 61 of the slice and through the head 68 of an adjusting rod 69. These adjusting rods extend upwardly to the top of the slice, being provided with an offset portion 13 which carries them to the front side of a stiffening flange 1|, secured to the slice and extending substantially the full length thereof. The upper end of each of the adjusting rods is screwthreaded and passes through a suitable aperture formed in the horizontal flange of the member 60 at the upper edge of the slice. Each bolt is provided with an adjusting nut 12 at each side of this flange, whereby the rod may be raised and lowered. Throughout the length of theslioe and the slice memberthere are provided a number of-these adjusting rods, whereby'the working face of the slice member 65 may be adjusted throughout its length to aflne. degree of accuracy. If desired.

slice member will not only be stiffened, but the" adjusting movement of the rods 68 will be more evenly distributed across the working edge of the member. I d

A deckle I5 is provided at each side of my outlet box and comprises an angle iron 16 and a piece of flexible material, such as rubber, in the form of a strip 8| which is secured to the vertical-leg 11 of the angle by means ofa number of bolts,"

which pass throughgthe vertical leg and-,the,

clamping bar". The innerends of the deckle angles'are secured to the outside face of each of the side wallslll and 2| by means of cap screws 30. These screws are passed through the legs 11 of the angles and the upper ends 38 of the'fa'pron,

and are screw-threaded into the side walls. Since the apron does not extend back-to the end of the angle, a filler 82 of the. same material and thickness as the apron is placed between the side wall and the inner leg of the angle at a point where the rear cap screw-88 is located. A wedge-shaped filler 83 is provided on the inside of each deckle and, as shown in Fig. 6, extends forwardly from the. vertical edge 48 of each of the side walls 28 and 2| and meets and joins the inner face of the flexible strip 8| of the deckle at-some point in front of the edge. Each ofthese wedge-shaped flllers ispreferably located between the clamping bar 18 and the flexible strip 8| of the deckle and thus provides smooth surfaces for the passage of the pulp as it moves out from under the slice forwardiy on the screen and between the deckles. The rearwardly projecting ends of the angles 15 of the deckles I4 are each preferably provided with slotted holes 84 through which the cap screws 88 pass, whereby the lower working edges of the flexible strips 8| of the ,deckles maybe, adjusted to the upper surface of the screen. The bolts I8 which hold the flexible strips 8| in place upon the decklesare passed through vertically. ar-

ranged slots 85 formed in the leg ll of the angle 18, whereby the clamping plates "and the flex-- ible strips 8| may be suitably adJusted.-- Each of the deckles is supported in its working position.

the pivotal points 82,. therefore, are located some distance-back from the forwardedges of the walls as of the head box'88, whereby the outlet box 88 is in telescopic relation with the head box 85 and may thus be moved from the full line position of Fig. 8 to the dotted line position thereof.

In these flgures I have also shown suitable' means for conveniently elevating the forward end of the outlet box. .These means comprise a shaft 88 extending preferably-"across the full width of the box and mounted in suitable bear ings 81 carried by the platform 8|. On this shaft is mounted anumbr of earns 88. These cams are preferably eccentric in form and are so designed that, when in'theirmaximum" positions, the outlet box will be moved to the dotted line position of 8.: Each of these cams is preferably provided with a flattened surface 88 for engagement with the outlet box when occupying its maximum position, whereby when in such position, the cams will be held in place by such flattened surfaces and thus be-prevented fromv accidental rotation "caused by the weight of' the outlet box. Suitable operating means are located at some convenient point on .the' shaft 88,and, as clearly shown in Figs.-8 and 9,

these may comprisea ratchet wheel I88 and an operating arm |8|. ty' mounted upon the end of the shaft and is engaged with the ratchet wheel by means of a spring-pressed ratchet pawl I82. A locking ratchet pawl I88 is carried by a bracket I84 .secured to the forward edge ofone of the side walls 85 of the head box, and serves to retain the ratchet wheel in any position to which it is operated-by the operating arm I8I.

vthe upper ends of the braces ried bythe platform 12.. when vint; the wire screen,

The operating arm is loose-:

a suitable packing strip I85, whereby thejoint across the bottom. ofv the outlet boxwill be-sealed when the box .is in its normal position.

' From the foregoing," it will be obvious thatwhen Theplatform is provided near its rear end with it is desired to replace the wire screen on a Fourdrinier machine to which my invention has been applied, it is only necessary to remove the deckles I4. which can be easily and quickly accomplished by .simply removing the two can screws an, the bolts 58., and the-bolts securing 8 6 to the outlet box I I..- After the deckles are. removed, the hand wheel 44 is operated, and, through the medium of the gear pinions 51 and racks 58', the outlet let box maythus be drawn to the dotted line positionlshown in Fig. 1, where the screen will be accessible for easy and quick removal. when the outlet box is being drawnback into box, the same will slide upon the tracks 25 carg the screen II has been replaced, it is only necessary to operate the hand wheel in ,theopposite direction to cause the outlet box tobe movedforwardly to that shown in r n lines.

its operative positionor in Fig. 1,-whereupon the deckles I5 may be re- "assembled in position. I I

Theangleiron 28 along the rear-edge of the bottom 24 ,of the outlet box will act as stop as it comes in contact with the rear edge of the platform I2, the packing. 28 servingto seal the joint atthis point. by contact with the angle. when the deckles are removed, it will beclear that the apron 3| will be heldinplacebecause the clamping plates 31.. andscrews 38 are not disturbed. It will be obvious that when replacas above described/no adthe head 15 box II is drawn into the head box-I8. The outiustments .are necessary in replacing the and-the entire operation may be accomplished in a very. short time and with very little'labor.

When it is desired .to replace the wire screen I8 of the form ofinventionshown in Figs. 8

and 9, the decklesfi operating handle I 8 I having been removed, the is raised'and lowered to cause the ratchet. wheel I88 to be rotated so as to bring the cams 88 fromtheir inoperative positions, shown in Fig. 9, to their maximum operative positions shownby dotted lines" in Fig. 3. Suchoperation'of the cams will cause the forward end of the outletbox 88 to be "elevated to the dotted: line portioned that between the bottom ofv the outlet box and the breast roll to enable-the workmen to quickly change the wire screen without any interference.

While I have specified rubber as being em ployed for the apron 8| and for the flexible strips 8| of the deckles 15, it is possible to use canvas or other fabric which has been properly treated to make it waterproof.

- Obviously, these and other modifications of the details herein shown and described maybe made position. The cams are so pro-' there will be sufficientclearance without departing from the spirit of my invention or the scopeof the appended'claims, and I do not, therefora'wish to be 'limitedtothe exact embodiment herein shown and described, the form shown'being merely a preferred embodiment thereof.
